The incident was reported around 9:44 p.m. on Aug. 18 in the 2000 block of East Broadway Avenue in Fruitport Township.

Police said the victim was struck by a vehicle driven by a 25-year-old man. Both involved are Muskegon County residents. The vehicle driver was not injured in the crash, but the bicyclist was transported from the scene by Pro Med to a local hospital, then air lifted by Aero Med to Spectrum Health in Grand Rapids. The bicyclist had multiple injuries, police said.

Authorities said in a press release that bicycle lighting is required for night riding, especially in unlit areas, and the bicycle in this incident did not have lighting.

"The area where this incident took place is an unlighted portion of roadway. The bicyclist did not have a light on his bicycle (required by law during darkness), and he was not wearing high visibility or reflective clothing or a bicycle helmet (recommended). The crash is still under investigation," the press release stated.

Additional information wasn't released by the police department Tuesday morning. The incident is still under investigation.
